or so says some sage.
Way back in the dinasaur age of December 1977 Ken Thompson used graphics when he wrote a manuscript on the UNIX Implementation as found in Bell System Technical Journal,
Jul/Aug 1978,
Vol.
57,
No.
6,
Part 2.
(Yes I have a copy and for the young folks,
there was only one phone company back then.)

My calander has flipped to 2009 and yet I find no graphics displayed in any documentation as displayed at http://search.cpan.org.

This is 32 years!!!

I find this a major step backwards - and most especially as we continue to push the levels of complexity.
If a module writer really wants to provide better documentation with graphics,
then there should be some method for it to be displayed at http://search.cpan.org.

The following snippet would be nice.
If you are formatting in html,
then you get an image,
and if in text,
then a note that there was an image.
In pod,
I do not believe that there is an if{}else{} type clause,
which would be nice,
ie if(html){do this}else{do that}.
Hence the text "block".
